Two reviews have recently been published covering the use of NMR for food authentication applications.
In this review (purchase required), the key applications of NMR in food authentication, described in the literature in the 2019–2024 period, are summarized, with emphasis on food metabolomics, complementary tools such as other analytical platforms, and chemometric models.
The authors argue that food metabolomics offers enormous opportunities to obtain detailed information that can be correlated to the composition of foods. NMR analysis allows the comprehensive monitoring of the molecular profile of hundreds of metabolites in foods in a single experiment, with high repeatability and accuracy. They conclude that a validated nontargeted NMR workflow is still needed.
This article (a chapter within an e-book about NMR applications in environmental analysis) covers NMR applications for both food authenticity and contaminant testing. It gives a brief overview of NMR methodologies, examples and several applications concerning the detection of specific frauds in food and agricultural products. It covers both high resolution NMR coupled with chemometrics and low resolution and low field NMR techniques.
